Fibrous Vs Globular Proteins Bioninja
Image processing outline illustrated with data from the tiny pore-forming toxin lysenin. To capture the initial images, protein samples are transferred onto a copper mesh grid coated with a perforated carbon film. The sample is then flash frozen in ethane at −190°C, causing the water to vitrify and capturing the proteins in random orientations within the holes of the carbon film. A beam of electrons is then use to capture a faint trace image of the protein. The computer system…
